Figs. 6 to 9 show the manner of connecting and disconnecting the side register screw 8 with respect to the spiders It. The bracket 10 is secured to spider l6 and provides a rotatable mounting for a shaft H, one end of which carries a double pathed cam 12 and to the other end of which is clamped an arm 13. The free end of the arm 18 carries a handle 14 having a spring-pressed retractable dowel pin 15 adapted to fit in a hole in the spider i6. Two studs 16 secured to split nuts ll fit in the two cam paths in the cam 12. Therefore the oscillation of the cam 12 separates the split nuts TI or brings them together on the screw part of the side register screw 8. These features are duplicated on the other end of the machine so that both split nuts can be connected with the screw 8 or either of them as desired. They are closed together whenever the dowel pin 15 is located in its hole in the spider and in that position the rotation of the side register screw 8 will move the spiders along the shaft 6. In this manner any position of the spiders may be obtained by leaving either one of the dowel pins 15 in its hole and rotatingthe side register screw. Both of the spiders can be moved along in the same direction for side register by leaving them both connected. This is a useful feature as it occurs some times that a fractional width roll on one side of the press for one edition has to be run on the other side of the pres." for the next edition. Heretofore in such a case it has been necessary to strip the reel .of all rolls, move the two spiders individually and reload the reel. With my construction, however, it is only necessary to press a button and the motor 28 will operate to move the roll-filled reel from one side of the machine to the other with practically no loss of time and no effort.

In the construction shown, covers 18 and 19 on each of the three spindles and a center cover 80 are provided on one spider, which is adapted for a web splicing device. These covers can be made removable or made integral parts of the spider I6.

As the side register motor 23 rotates with the reel it is necessary to use selector rings for distributing electric power properly. This is done by employing an insulation ring 31 secured to the plate 25. This insulating ring has contact rings 88, five being shown but usually only two or three are used. against these-rings 88 with spring pressure pro- .duced by springs 40. A cap 4i is used to back up the whole device and this cap is mounted in a sleeve 42 of bakelite or other insulating moldable material. A wire may be attached for supplying electric power through the brushes 38 to the contact rings 88 and thus to the motor 28 by means of a connection 48. This connection is soldered to a sleeve 44 to provide the necessary actuated by a shaft 58 operated by hand by an arm 54 thereon. This arm is provided withv a handle 55. which carries a retractable dowel '4 Carbon brushes 88 bear straps.

fitting in a hole in the side of the chuck to hold the chuck in place when the paper roll is locked up. On the shaft 58 is a pinion 52 adapted to move the cylinder 48, and therefore the chuck, back and forth.

The shaft 48 carries a mounting for ball bearings 51 and the ball bearing supports the chuck, which is held in place by a sealing plate 59 secured to the chuck. The tapered end of the chuck 58 is so constructed as to fit in the paper core of the roll and thereby provides a support for one end. The shaft 49 is longitudinally adjustable by means of an adjusting screw stud 60,

' the inner end of which is threaded into the end of the shaft 49 and to the outer end of which is fixed a hand wheel SI for adjusting it. There is a recess in a cover plate 62 fixed to the end of the cylinder 48 in which recess is located a shoulder on the screw stud 60 to hold it against end motion.

, On the other end of the machine the spindle bearing for the roll comprises a shaft 63 on which is secured the complementary chuck 64 for the same web roll. The shaft is carried in ball bearings 85, being held in place against the shoulder on the shaft by spacers 6'1 and 68 and a lock nut 68. The particular construction of parts at this end is adapted for installation with the parts of an automatic pasting machine, particularly for the automatic paster, which is the subject matter of my prior Patent No. 1,843,469.

It will be understood that a simple reel could be made not particularly adapted for use with this automatic machine in a less elaborate manner.

Referring to Figs. 16 and 17 a limit switch construction is shown, which prevents the spider from being jammed against the bearing box at the end. This is shown in the form of a shoe 8i guided in an upright position by a bracket 82 secured to the end bracket. This shoe is pinned to a switch rod 88 which is spring-pressed and has its bearing in the bracket 82 and also in the end bracket. The switch rod 88 is provided with a collar 84 against which the spring presses and it bears against a roller 85 on an arm on the shaft of the limit switch 88.

It will be seen that the switch rod 83 is springpressed to the right in the position shown until the cover plate 80' of the spider bears against the upper part of the shoe ll which opens the switch 86 and disconnects the power automatically from the motor 18. A similar switch construction is used on the other end of the reel, as shown in dotted lines in Fig. 2.

The motor 23 is reversible and of course, these ,switches operate to stop the motion of the spider longitudinally of the shaft, only in one direction in each case: that is, the direction in which they move. This arrangement is provided, of course, to prevent damage. It is possible to move the spider or spiders in the opposite direction away from the limit switch as is customary with limit switches of this kind.

In connection with this auto reel simple tension members 81 are employed in the form of The lower ends of these straps are detachably mounted by hooks 88 latching over a shaft 88 secured by brackets 90 to the foundation or floor. The other ends of the straps are secured to the ends of individual levers 9|, which are pivotally mounted on the frame of the machine and carry rods 82 at their other ends for the support of a series of removable weights 83. Four tension members are shownas it is convcnient to unlatch one each for each page width of narrowing of the paper when fractional width rolls are used. When a half width roll is used, two tension straps are used, for a. three-quarter roll, three of them are used. They are very easily thrown out of operation by unlatching the hook 89 and hanging the belt up over-a pipe 94 which extends across the reel and is mounted on the columns l.

It will be seen that a rotatable paper roll-supporting device is provided which is sturdy in construction, particularly on account of the brackets 2, uses little or no floor room because it is mounted on the columns of the press, within the boundaries thereof, carries diseonnectible means for moving the spider longitudinally on the reel shaft by power and constructed to be used in connection with very simple tension members which can be put out of operation and brought back into operative position very easily and quickly. Furthermore, it can be located high enough in the machine so as to leave a clear floor space underneath the reel for cleaning and repairing. i

The details of the spider shifting device, that is, the double nut and two path cam arrangemcnt, constitute the subject matter of my previous Patent No. 1,957,122, filed May 12, '1932, patcnted May 1, 1934, and is claimed herein only in combination with the other features.

Although I have illustrated and described only one form of the invention 1 am aware of the fact that modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore I do not wish to be limited in this respect otherwise than as set forth in the claims, but what I claim is:-- i
